The nickel content of the coating is 12-15%, and the process operation current density area is wide, especially the low current density area.
3. High current efficiency, stable up to 50 ~ 60%, suitable for hard fasteners.
4. Zinc-nickel alloy coating hydrogen embrittlement is very small, suitable for high strength steel plating.
1. Used to remove metal impurities in acidic zinc plating solution.
2. Easy to use, can be added in the normal plating operation, no need to stop processing.
DK-778 Alkaline zinc plating solution comprehensive purifier
1. Used to remove copper, iron, lead, tin, chromium and other heavy metal ions and organic decomposition products in alkaline zinc plating solution.
2. plating solution purification thoroughly, high efficiency.
DJ-96 Alkali zinc fog suppressant
1. Used to inhibit the escape of alkali mist in alkali zinc plating solution.
2. The inhibition rate of alkali mist can reach more than 90%, which can effectively improve the working environment of the production workshop.
DJ-97 Alkali zinc moving and removing impurity water
1. Used to eliminate the phenomenon of blackening or darkening in the low current density area caused by organic impurities.
2. It can significantly improve the dispersion ability of the plating solution.
1. Used to remove organic impurities and heavy metal impurities in alkaline galvanizing solution.
2. Easy to use, can be added in the normal plating operation, no need to stop processing.
1. Used to remove heavy metal impurities in alkaline zinc plating solution.
2. Easy to use, can be added in the normal plating operation, no need to stop processing.
DB-931A High corrosion resistance trivalent chromium color passivating agent
1. This passivator has passed SGS testing, does not contain hexavalent inscription, and complies with RoHS regulations. At the same time, it also meets the requirements of IEC62321 international electrical standards. It is the best choice for color passivation products exported to Europe and America.
2. When the thickness of the zinc layer is ≥ 10 microns, the resistance to NSS≥ 150 hours.
3.DB-931A passivating agent operating process range is wide, normal temperature use, excellent fast, easy to maintain and control. It is suitable for the application of manual line or automatic line of acid zinc, alkali zinc roll plating or hanging plating.
DB-952 High corrosion resistance trivalent chromium color passivating agent
1. This passivator has passed SGS testing, does not contain hexavalent inscription, and complies with RoHS regulations. It also meets the requirements of IEC62321 international electrical standards. It is the best choice for color passivation products exported to Europe and America.
2. When the thickness of the zinc layer is ≥ 8 microns, the resistance to NSS≥ 120 hours.
3. Strong anti-rust performance, high temperature resistance; baking at 200 ℃, the appearance rarely changes, and its NSS resistance can still exceed 72 hours. It makes up for the defect that the corrosion resistance of hexavalent chromium passivation film decreases after heating, and it still has excellent corrosion resistance after secondary processing.
4.DB-952 passivator operating process wide range, at room temperature, excellent fast, easy to maintain and control. It is suitable for the application of manual line or automatic line of acid zinc, alkali zinc roll plating or hanging plating.
